ADDRESSING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 236,001, dated December28, 1880.

Application filed February 6, 1880.

To all whom it may concern Be it known that I, FRANCIS A. DARLING, ofBrooklyn, in the county of Kings and State of New York, have invented anew and useful Improvement in Addressing-Machines, of which thefollowing is a specification.

The object of my invention is to provide improved apparatus for rapidlyand accurately printing the names and addresses of persons and placesfor directing newspapers and other periodicals to individuals and clubsof subscribers.

The invention consists in the construction and combination of theaddress-blocks, the galleys, and the various parts of the feeding andimpression mechanism, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a front View of myimproved addressing-machine, parts being shown in section. Fig. 2 is atop or plan view of the same, partly broken out. Fig. 3 is across-section through one of the printing-blocks, the galley, and galleyguide, the section being taken through the line as a: of Fig. 2. Fig. 4is a detail cross-section through the line 3/ y of Fig. 2, showing aside or edge view of the printin g-block clamp secured in position tothe galley. Fig. 5 shows an end view of the galley with its side framein section. Fig. 6 is a cross-section of the printing-block clamp, takenon the line 2 z of Fig. 4, and inverted in position as compared with thelatter figure, or in the position corresponding with that of the blocksin Figs. 7 and 8, in which it is held when the clamp is fastened to thegalley.

Similar letters of reference indicate corresponding parts in the severalfigures.

The addresses are engraved or stamped upon parallelopipedon woodenblocks A, having axial wires a projecting one from either end of eachblock. For clubs of subscribers the post-office address common to allthe members of the club is stamped upon a block, (which is larger, ormarked with a saw-slit upon the back, as shown at a,for betterdistinction from the rest,) such as shown in Fig. 7--for instance, thus:Richland Station, Lebanon 00., Tenn.,and printed on the main wrapperinclosing together all the papers for the individual members of theclub. The name of each member is stamped upon a smaller separate block,as illustrated in Fig. 8-for instance, F. Cooper, Thomas Fraziertogetherwith the date of expiration of his subscription, thus: 22 Jan, 80, 31Dec., 79.

To facilitate rapid reference to the entrybook of subscribers withoutneed of looking through its index-pages, I have added at the left cornerof the face of each block, below the subscribers name, the number (24,124, or &c.) of the page in the book on which his name and accountappear. A series of blocks, A, are then inserted face upward, to rest bytheir end pins, to, in the channeled sheet-metal side pieces, I), of aso-called galley, B, joined at the ends to keep the channeled sides I)at the proper distance apart by riveted cross-pieces b, shaped as shownin Fig. 5. The'inserted blocks are pushed together side by side andretained in said position by being held between one of the end bars,b,of the galley and a stop-clamp, O, secured to the galley at the otherend of the series of blocks.

The clamp O is made of two cast-metal plates, 0, curved against eachother, and secured together by a central rivet, 0, upon which is pivoteda button, 0 tightening against two cam-ridges or curved ribs, 0 whichare formed on the outside of one of the plates 0, one on each side ofthe pin or rivet 0. The clamp is inserted across the galley B to claspbetween the ends of the pair of plates 0 the edge of the side piece, b,which forms one wall of the channel or groove b and is made to pinch thetwo opposite edges of the two side pieces, I), as shown in Fig. 4, byturning the button 0 up on the highest portion of the ribs 0 Thisprevents the series of blocks A from getting apart laterally. Thegrooves bare made sufficiently wider than the diameter of the end pins,66, to allow of sliding any one of the blocks A vertically to projectits printing-surface from the flush surfaces of the adjacent blocks asuitable distance to give room for separate impression without blottingthe paper printed upon by getting it in contact with the inked surfacesof the adjacent 'blocks.

In order to'successively project the blocks for printing and withdrawthem after the impression, I provide the following mechanism:

To a suitable vertical frame, D, is attached a horizontal plate, E,having parallel vertical flanges arranged at such a distance apart thatthe measure between their outer edges is just enough less than the widthof the opening in the galley B to allow of placing the latter above theplate E, with the side pieces, 1), outside of the flanges 0, thuscausing the said flanges to guide the galley when the latter is slidalong over the plate E.

The printing-surface of the blocks A being inked by means of an ordinaryinking-roller, the galley 13 is im'erted (to bring the face of theblocks A downward) and placed over the guide-plate E, with the sides I)outside of the flanges 0, so that galley and blocks together aresupported upon the said flanges c by the series of pins a, and may beslid forward in direction of arrow 1 by a pawl, F, acting upon the pins(1, while a cut or depression, 0. in the flanges 0 will allow the block,when its end pins are passing in the said depression, to sink or bepushed down with its face a distance below the surface of the otherblocks, in which position it is held while the impression is being made.

G is the table upon which the wrapper or other paper is placed to beprinted, and is attached to the upper end of a vertical rod, 1, arrangedto slide in a lug or other guide, (I, on the frame D. The lower end ofthe rod is intended to be attached to a treadle or footlever, (of thefirst class,) so that by pressure on the treadle the table G may beraised to press the wrapper against the inked face of the block inposition to receive it. Fig. 1 shows the table G raised in position toimpart the impression.

The bottom plate of the galley-guide E has an opening, through which thecentral block descends and is retained during the impression. At theside of the said opening the plate E is bent down to form (orhasattached to it) a spring, 0 which serves to release the printed paperfrom the face of the block on the downward movements of the table G. Thegalley is steadied against vertical oscillation by the pressure ofhalf-elliptic springs H, attached to the frame D, and pressing upon theside pieces, I), of the galley B.

The feed-pawl straddles the length of the blocks A and has notched endsf, engaging with the central pins, 01, at either end of the block, toslide it along until it reaches the central cuts,c,in the tlanges e,where itis pushed down and held in position for printing by anoscillating cam, I, and stop-block J, actingon the upper side or back ofthe block A. The pawl F is pivoted by a lag, f, to an arm, 7:, ofashaft, K, having its bearing in the frame D, and on whose other end, inthe rear of the frame D, is secured a cog wheel or segment, k, meshingin the teeth of a segmentallytoothed bar, L, which is pivoted at l onthe back of the frame D.

To the rear edge of the table G is attached a pin, m, on which ismounted a roller, M,

which, as the table ascends, comes in contact with a welt orcam-projection, l on the edge of the segment-bar L, and, in passing thesaid projection, presses the said bar L laterally, thereby turning thesegment 7a the part of one revolution required to give sufficient throwor feed movement to the pawl F. The frame D has a vertical slot, at, outthrough it to allow the roller M to pass up and down.

N isanother segmentally-toothed bar, pivoted at l upon the same pivot asthe bar L, and having a similar cam-projection, a, coinciding, when inthe position shown in Fig. 1, with the projection l, and acted uponsimultaneously with the latter by the ascending roller M, to turn a cogsegmentor wheel, 0, (mounted upon the same shalt, o, as the cam l,) andwith it the cam I, into the position of its full downward throw, or asshown in Fig. 1. The shaft 0 of the cam and wheel I O is journaled inthe frame 1), parallel with the axis of the block A, in position forprinting and at right angles to the axis of the rod g.

To a bracket, P, attached to the frame D is secured one end of a spring,Q, to whose other end is fastened the stop-block J in position to beinterposed between the cam land the central block, A, and resist theforce of the impression.

Each successive feed movement of the pawl F causes the depressed blockjust printed with to travel by its end wire, a, up the inclined edge ofthe depression 0 of the flange 0 until it resumes the position in whichits horizontal surfaces are flush with those of the other blocks.

\Vhen the table Gr descends, a spring or springs, 11, (acting upon thecog-segment bars L N on their edges opposite to those against which theroller M acts,) causes the wheels and cam 7; O I to turn in thedirection of arrows 2, thus withdrawing the pawl F to take a new hold onthe pins a for a subsequent feed, and releasing the block Ajust operatedwith, the stop-block J being raised by the spring Q, on the withdrawalof the pressure of the cam l. \Vhen one galley has thus been fed throughthe machine another is substituted, and so on until the whole issue isaddressed.

It is evident that the machine may be arranged to print by the downwardmovement of the printing-block upon a stationary plate or table; or theblocks A may be reversed and motion imparted to or against them to printon the upper side; but I prefer the construction as before described.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- 1. The addressing-blocks A, having axial end pins,to, in combination with a retaining galley or frame, B, having channeledside bars, I), in which the retaining-grooves Z) are wider than thethickness of the said end pins, to, to allow of vertical movement of theblocks while in the galley, substantially as and for the purpose setforth.
